FIELD OF THE INVENTION

The invention generally relates to ventilation systems and methods, and more particularly to selectively configurable climate control systems and methods for use in data centers and the like.

BACKGROUND

A data center (or other physical space) beneficially has, where possible, an optimized heating and cooling infrastructure. Maintaining data centers at desired temperatures (e.g., set points) helps prevent computer hardware (e.g., IT infrastructure) from overheating and malfunctioning. To this end, many data centers are cooled to relatively low temperatures (e.g., 65° F.) to increase equipment reliability and useful life, and to avoid downtime for repair and/or replacement.

However, current climate control systems are largely inefficient. Data centers typically have hot spots where IT equipment operates. Conventional cooling systems cool the entire data center to a temperature well below the set point so that IT equipment operating in the hot spots does not exceed the set point. This increases operational costs and wastes energy.

More specifically, conventional climate control systems for data centers typically utilize static (i.e., fixed) ducts and vents/diffusers. Usually this is achieved through the use of multiple air conditioners, heaters, vents or blowers. In the current art, a centralized air conditioning or ‘forced air’ system requires the use of static conduits or ducts. These ducts are usually installed to blow hot or cold air from a centralized air conditioning or heating unit to specific areas of the building. One problem with this known solution is that these ducts cannot easily be changed or rerouted to accommodate changing conditions on a room. For example, ducts are usually embedded in the ceiling, walls, or floor, and therefore require time-consuming intervention to re-route.

Another problem with fixed systems is that they are highly inefficient. In data centers, the hot spots are routinely changing location depending on which IT equipment is running at any given time. For example, some IT infrastructure in a first area of the data center may run during the day, while other IT infrastructure at a different area of the datacenter operates at night. To accommodate such moving hot spot targets, existing systems resort to a sort of ‘overkill’ by cooling the entire volume of the data center to well below the set point, which increases operational costs. Moreover, with the increasing awareness and desire to operate in a green manner, such excessive use of energy is undesirable.

Distributed cooling systems represent an alternative or supplement to fixed-duct systems, in which individual local units (similar, for example, to a window air conditioning unit) are moved around within the data center depending on the localized cooling needs. However, these decentralized systems are expensive to manage and maintain. Moreover, there is a certain amount of time required to re-position local cooling units within a data center, such that decentralized systems cannot adapt quickly to changes in temperature of different areas in a room.

Accordingly, there exists a need in the art to overcome the deficiencies and limitations described hereinabove.

DETAILED DESCRIPTION

The invention generally relates to ventilation systems and methods, and more particularly to selectively configurable climate control systems and methods for use in data centers and the like. Embodiments of the invention comprise a dynamic duct system including partitions that are selectively extendable between two structural elements to create a duct between the structural elements. By selectively controlling actuators to extend or retract selected ones of the partitions in a coordinated manner (e.g., via computer control), a targeted air delivery system may be provided. In this manner, implementations of the invention provide a highly efficient climate control system that is reconfigurable both quickly and inexpensively. Accordingly, embodiments of the invention may be used to implement a green data center that is economical to operate and reduces energy waste, while still maintaining computing infrastructure at desired operating temperatures.

FIG. 1 shows a perspective view of an exemplary dynamic duct system according to aspects of the invention. The system 5 includes a first structural element 10 and a second structural element 15. In embodiments, the first and second structural elements 10, 15 are substantially planar, although the invention is not limited to this configuration, and any suitable shapes can be used within the scope of the invention. The first and second structural elements 10, 15 may be composed of any suitable material (e.g., ceiling tiles, plasterboard, fiberglass, plywood, metal, plastic, compressed fiberboard, etc.).

In embodiments, the system 5 is arranged adjacent or near a room 20, which may comprise, for example, a data center, or any other type of area for which ventilation may be provided. In the embodiment depicted in FIG. 1, the system 5 is arranged above the room 20, such that the second structural element 15 constitutes a ceiling of the room 20. However, the invention is not limited to this configuration, and portions of the system can be arranged in any suitable spatial relation to the room 20, such as, for example, at the floor, at a wall, or at various combinations of at least one of the ceiling, floor, and walls.

The first and second structural elements 10, 15 are spaced apart from one another such that a space 25 is formed between them. The space 25 constitutes a volume in which dynamic ducting according to aspects of the invention may be arranged and re-arranged according to ventilation requirements of the room 20.

In embodiments, the first structural element 10 is divided into a grid as depicted in FIG. 1. In the exemplary embodiment shown in FIG. 1, the grid is a three-by-three grid having nine grid areas labeled GA1, GA2, . . . , GA9. The invention is not limited to this size grid, and any suitable grid can be defined in the first structural element 10. In embodiments, each grid area (e.g., GA7) has four rectilinear sides 40 defining its perimeter. Associated with each one of the sides 40 of each grid area GA1, GA2, . . . , GA9 is an extendable and retractable partition generally referred to with reference number 45. For clarity, only six partitions, specifically referred to with reference numbers 45A, 45B, . . . , 45F, are shown in FIG. 1 and described herein. However, the description of these representative six partitions 45A, 45B, . . . , 45F applies to all of the partitions 45 of the system 5. Adjacent grid areas (e.g., GA1 and GA2) may share a common partition (e.g., 45A) along common side 40, such that in the exemplary embodiment shown in FIG. 1, there are a total of twenty four partitions 45 (although only six partitions 45A, 45B, . . . , 45F are shown for clarity).

Each partition is selectively moveable between an extended position and a retracted position. In the extended position, the partition 45 extends into the space 25 between the first and second structural elements 10, 15, for example, as depicted by partitions 45B, 45C, 45E, and 45F in FIG. 1. In the retracted position, the partition 45 is arranged so that it does not extend between the first and second structural elements 10, 15, for example, as depicted by partition 45D in FIG. 1. In the specific example shown in FIG. 1, the partitions 45 move between the extended and retracted positions by translating vertically (e.g., perpendicular to the plane of first structural element 10). For example, partition 45A is shown between the extended and retracted positions. However, the invention is not limited to this configuration, and other movement arrangements and retracted positions are useable, as described in greater detail below.

According to aspects of the invention, by selectively controlling which partitions 45 are in the extended and retracted positions, a duct 50 can be dynamically created in the space 25, as depicted in FIG. 2. More specifically, by arranging partitions 45A-F in the extended position (e.g., extending between the first and second structural elements 10, 15), a duct 50 that defines a flow path FP can be provided. Although the first and second structural elements 10, 15 are shown as transparent, they are substantially solid members such that the combination of the first and second structural elements 10, 15 and the extended partitions 45A-F creates a rectangular duct 50 around flowpath FP. A different duct can be arranged in the space 25 by moving partitions 45A-F into the retracted position and moving other partitions into the extended position.

FIGS. 3 and 4 show top down views of exemplary modes of operation of the invention, in which the dynamically changeable ducting of the inventive system is demonstrated. In FIGS. 3 and 4, the upper element 10 is divided into thirty six grid areas, referred to generally as GA. Partitions 45 in the extended position are depicted by cross-hatched areas; all other partitions are in the retracted position. Accordingly, FIG. 3 shows a first duct 60 connecting locations LA, LB, an LC. In the exemplary embodiment shown in FIG. 3, a fluid source 110 (e.g., HVAC unit, blower, exhaust, etc.) may be fluidly connected to location LA by, for example, static ducting 112. In this manner, fluid (e.g., cool air) can be moved from location LA to locations LB and LC via first duct 60.

Moreover, vents 65 may be provided in second structural element 15 to move the fluid from the source 110 into the adjacent room (e.g., data center) to provide targeted cooling in the room. The vents 65 may be static (always open) or adjustable (e.g., between open and closed). In embodiments, the movement of the partitions 45 to the retracted or extended positions may be controlled by a controller 120 (such as, for example, a computing device described in greater detail below) that transmits control signals to actuators associated with each partition 45. In further embodiments the vents 65 are adjustable and may be controlled by the controller 120 transmitting control signals to actuators associated with each vent 65.

FIG. 4 shows a second exemplary mode of operation in which the cooling requirements of the room have changed. Whereas cooling is required in the vicinity of locations LB and LC in the first mode (FIG. 3), cooling is required in the vicinity of locations LB, LD, and LE in the second mode (FIG. 4). Such a change in cooling requirements may be caused, for example, by IT equipment in different areas of the room turning on and off.

Accordingly, in the second mode, the controller 120 sends actuation signals to appropriate ones of the partitions 45 to move appropriate ones of the partitions 45 to either the extended or retracted state to create second duct 70. In this manner, fluid (e.g., cool air) is provided from source 110 to locations LB, LD, and LE via second duct 70 and vents 65 located along second duct 70.

As can be seen from this example, implementations of the invention provide targeted climate control (e.g., cooling) that is quickly and easily adjusted to meet the changing needs of a data center. The invention is not limited to the two modes of operation described in FIGS. 3 and 4, but rather any suitable duct or combination of ducts may be created by moving appropriate ones of the partitions into the extended or retracted positions. Moreover, although the arrangement of first and second structural elements 10, 15 is shown to be square (e.g., six by six) any desired geometry can be used.

Furthermore, vents 65 are not limited to the locations shown in FIGS. 3 and 4. Instead, any number of vents 65 can be located at any desired locations in at least one of the first and second structural elements 10, 15.

In embodiments of the invention, each partition 45 is associated with an actuator for moving the partition 45 between the retracted and extended position. FIG. 5 shows an exemplary arrangement for moving vertically moveable partitions (e.g., as shown in FIGS. 1 and 2), in which an actuator 75 comprises an electric servo motor 80 with a pinion gear 85 attached to a rotatable shaft 90. The pinion gear 85 may operatively engage a rack gear 95 affixed to the partition 45, such that rotation of the servo motor drive shaft 90 causes up or down movement of the partition 45. Alternatively, the vertical motion of the partition may be provided by a servo motor operatively connected to the partition by a scissor-lift linkage mechanism (not shown) or equivalents thereof. In either case, the actuator (e.g., electric servo motor) may receive power from any suitable power source and may receive signals from controller 120 in any suitable manner (e.g., via electrical connection 97).

Alternatively, as depicted in FIG. 6, each partition 45 may be hingedly connected to the first structural element 10, such that the partition 45 is pivoted between the extended position and the retracted position. In this embodiment, the retracted position (shown in dashed line) is where the partition 45 is pivoted upward to lie near or against the first structural element 10, such that the partition 45 does not provide any substantial flow diversion in the space 25 between the first and second structural elements 10, 15. The actuator 75, in this case, may comprise an electric servo motor 80 having a gear 85 attached to a rotatable shaft 90. The gear 85 may operatively engage another gear 115 on a hinge axis of the partition 45, such that rotation of the servo motor drive shaft 90 causes pivoting of the partition 45.

In the embodiment shown in FIG. 6, the partition 45 may additionally be hinged (e.g., via suitable linkages, not shown) about a second axis that is generally orthogonal to the first and second structural elements 10, 15 and the hinge axis of gear 115. In this manner, the partition 45 may be moved from the retracted to the extended position (e.g., as shown in FIG. 6), and then rotated 90° about the second axis. In this manner, a single partition 45 may be moved to plural different extended positions.

Additionally or alternatively, in the embodiment shown in FIG. 6, each of the partitions 45 associated with a particular grid area GA may be arranged to substantially overlap each other (e.g., lie one on top of the other in the center of the grid area GA) when all the partitions 45 of that grid area GA are in the retracted position. By keeping track of the position of each partition 45 (e.g., retracted or extended), and by appropriately moving each respective partition 45 between its retracted and extended position, a controller can selectively create any desired pattern of extended/retracted partitions 45 of the grid area GA.

The invention is not limited to actuation arrangements described above with respect to FIGS. 5 and 6. Instead any suitable configuration of partition and actuator may be used. For example, each partition 45 may comprise a plurality of hinged segments (e.g., similar to a garage door), in which the actuator causes the partition 45 to move (e.g., glide or roll) along tracks in the space 25 between the first and second structural elements 10, 15.

The controller 120 described above may be any suitable control device, such as a computing device, that is capable of transmitting actuation signals to each one of the respective actuators of the partitions 45. The controller 120 may include a CPU, memory, storage, etc., known to those of skill in the art. In embodiments, each respective actuator 75 may be assigned a unique identifier (ID), such that individual control of each actuator 75 is possible. More specifically, each actuator 75 may be: provided with a predefined ID (e.g., similar to a MAC address); assigned an ID (e.g., similar to a static IP address) by a user via programming of the controller 120; or, automatically assigned an ID by the controller (e.g., similar to a plug-and-play dynamic IP address) by way of programming of the controller 120. By having a unique ID associated with each actuator 75, the controller 120 can be programmed to send appropriate actuation signals to each individual actuator 75 (e.g., via electrical connections and/or wirelessly) to achieve substantially any desired configuration of extended and retracted partitions 45, to therefore create any desired duct between the first and second structural elements 10, 15.

FIG. 7 shows an illustrative environment 810 for managing processes in accordance with the invention. To this extent, the environment 810 includes a computer infrastructure 812 that can perform the processes described herein. For example, the controller 120 (described above) may comprise or be comprised within the computer infrastructure 812. In particular, the computer infrastructure 812 includes a computing device 814 that comprises an application 830 having a program control 844, which makes the computing device 814 operable to perform the processes described herein, such as, for example, providing control signals to actuators of partitions to create a dynamic duct with which to control temperature in a room sensed by sensors and/or according to a predefined cooling plan.

The computing device 814 includes a processor 820, a memory 822A, an input/output (I/O) interface 824, and a bus 826. The memory 822A can include local memory employed during actual execution of program code, bulk storage, and cache memories which provide temporary storage of at least some program code (e.g., program control 844) in order to reduce the number of times code must be retrieved from bulk storage during execution. Further, the computing device 814 is in communication with an external I/O device/resource 828 and a storage system 822B. The I/O device 828 can comprise any device that enables an individual to interact with the computing device 814 or any device that enables the computing device 814 to communicate with one or more other computing devices using any type of communications link. The external I/O device/resource 828 may be keyboards, displays, pointing devices, etc., which enable a user to adjustably control the climate in a room (e.g., data center) using dynamic ducts.

The processor 820 executes computer program code (e.g., program control 844), which is stored in memory 822A and/or storage system 822B. While executing computer program code, the processor 820 can read and/or write data to/from memory 822A, storage system 822B, and/or I/O interface 824. The bus 826 provides a communications link between each of the components in the computing device 814.

The computing device 814 can comprise any general purpose computing article of manufacture capable of executing computer program code installed thereon (e.g., a personal computer, server, wireless notebook, smart phone, personal digital assistant, etc.). However, it is understood that the computing device 814 is only representative of various possible equivalent computing devices that may perform the processes described herein. To this extent, in embodiments, the functionality provided by the computing device 814 can be implemented by a computing article of manufacture that includes any combination of general and/or specific purpose hardware and/or computer program code. In each embodiment, the program code and hardware can be created using standard programming and engineering techniques, respectively.

Similarly, the computer infrastructure 812 is only illustrative of various types of computer infrastructures for implementing the invention. For example, in embodiments, the computer infrastructure 812 comprises two or more computing devices (e.g., a server cluster) that communicate over any type of communications link, such as a network, a shared memory, or the like, to perform the processes described herein. Further, while performing the processes described herein, one or more computing devices in the computer infrastructure 812 can communicate with one or more other computing devices external to computer infrastructure 812 using any type of communications link. The communications link can comprise any combination of wired and/or wireless links; any combination of one or more types of networks (e.g., the Internet, a wide area network, a local area network, a virtual private network, etc.); and/or utilize any combination of transmission techniques and protocols.

The steps of the flow diagram described herein may be implemented in the environments of FIGS. 1-6 and implemented in the computer infrastructure of FIG. 7. The flow diagram may equally represent a high-level block diagram of the invention. The steps of the flow diagram may be implemented and executed from a server, in a client-server relationship, by computing devices in an ad hoc network, or they may run on a user workstation with operative information conveyed to the user workstation. Additionally, the invention can take the form of an entirely hardware embodiment, an entirely software embodiment or an embodiment containing both hardware and software elements. In an embodiment, the software elements include firmware, resident software, microcode, etc.

Furthermore, the invention can take the form of a computer program product accessible from a computer-usable or computer-readable medium providing program code for use by or in connection with a computer or any instruction execution system. The software and/or computer program product can be implemented in the environments of FIGS. 1-6. For the purposes of this description, a computer-usable or computer readable medium can be any apparatus that can contain, store, communicate, propagate, or transport the program for use by or in connection with the instruction execution system, apparatus, or device. The medium can be an electronic, magnetic, optical, electromagnetic, infrared, or semiconductor system (or apparatus or device) or a propagation medium. Examples of a computer-readable medium include a semiconductor or solid state memory, magnetic tape, a removable computer diskette, a random access memory (RAM), a read-only memory (ROM), a rigid magnetic disk and an optical disk. Current examples of optical disks include compact disk—read only memory (CD-ROM), compact disk—read/write (CD-R/W) and DVD.

FIG. 8 shows a flow diagram depicting steps of a method for providing air to a room in accordance with aspects of the invention. At step 910, a controller causes a first subset of a plurality of partitions to move into an extended position between first and second structural elements. This may be accomplished, for example, as described above with respect to FIGS. 1-6. More specifically, the controller may transmit actuation signals to appropriate ones of actuators associated with respective partitions to move the partitions to the desired position (e.g., extended or retracted) to create a first duct (e.g., first flow path) within a space between the first and second structural members. In this manner, fluid (e.g., cooling or heating air) can be provided to targeted areas of a room (e.g., data center) according to sensed temperatures in the room and/or according to a predefined heating/cooling plan.

Optionally, at step 915, the controller causes adjustable vents along the first duct to open or close. This may be accomplished, for example, by the controller sending actuation signals to appropriate ones of actuators associated with the vents located along the first duct. In this manner, selective ones of the vents along the first duct can be opened or closed as desired.

At step 920, the controller causes a second subset of the plurality of partitions to move into an extended position between the first and second structural elements. This may be accomplished, for example, as described above with respect to FIGS. 1-6. More specifically, the controller may transmit actuation signals to appropriate ones of actuators associated with respective partitions to move the partitions to the desired position (e.g., extended or retracted) to create a second duct (e.g., second flow path) within the space between the first and second structural members. In this manner, fluid (e.g., cooling or heating air) can be provided to targeted other areas of a room (e.g., data center) according to sensed temperatures in the room and/or according to a predefined heating/cooling plan.

Optionally, at step 925, the controller causes adjustable vents along the second duct to open or close. This may be accomplished, for example, by the controller sending actuation signals to appropriate ones of actuators associated with the vents located along the second duct. In this manner, selective ones of the vents along the second duct can be opened or closed as desired.

In embodiments, the room comprises a data center, the localized area comprises a hot spot, and the fluid comprises cold air for cooling the localized area. Moreover, the second duct may be different than the first duct. However, the invention is not limited to use with data centers, but rather can be used to provide localized fluid flow (e.g., air flow) into any desired area. For example, implementations of the invention could be used to provide localized air conditioning and/or heating to residential homes, conference centers, hotels, office buildings, stables, etc.

A computing infrastructure comprising a controller structured and arranged to: actuate a first subset of a plurality of partitions to extended positions between first and second structural members to create a first duct between the first and second structural members; and actuate a second subset of the plurality of partitions to extended positions between the first and second structural members to create a second duct between the first and second structural members, wherein each of the plurality of partitions is moveable between a retracted position and an extended position by a respective actuator associated with each of the plurality of partitions; in the extended position a respective one of the plurality of partitions spans substantially an entire distance between the first and second structural members; the retracted position is one of: (i) outside a space between the first and second structural members, and (ii) pivoted from the extended position to lie near or against the first structural member; when the retracted position is outside the space between the first and second structural members: a respective one of the plurality of partitions does not extend between the first and second structural members in the retracted position; the plurality of partitions move between the extended and retracted positions by translating perpendicularly to a plane of the first structural member; each said actuator is outside the space between the first and second structural members and comprises an electric motor with a pinion gear attached to a rotatable drive shaft; and the pinion gear operatively engages a rack gear affixed to a respective one of the plurality of partitions such that rotation of the drive shaft causes up or down movement of the respective one of the plurality of partitions; and when the retracted position is pivoted from the extended position to lie near or against the first structural member: a respective one of the plurality of partitions pivots about a hinge axis when moving between the extended and retracted positions; each said actuator comprises an electric motor with a gear attached to a rotatable drive shaft; and the gear operatively engages another gear on the hinge axis such that rotation of the drive shaft causes pivoting of the partition.
 17. The computing infrastructure of claim 16, wherein: the retracted position is pivoted from the extended position to lie near or against the first structural member; a group of the plurality of partitions are arranged with a grid area; and the group of the plurality of partitions overlap each other in a center of the grid area when all of the group of the plurality of partitions are in the retracted position.
 18. The computing infrastructure of claim 16, wherein: at least one of the first structural member and the second structural member is divided into a grid; and a respective one of the plurality of partitions, when in the extended position, is an only partition between adjacent grid areas of the grid.
